From Dutch daily NRC Handelsblad of 28 June:
The archaeologists of the Katholieke Universiteut Leuven [in Belgium] who found the animal, think this was a captive cat, not a tame cat.
Soon, their article will be published in the Journal of Archaeological Science.
At the cemetery, also remains were found of baboons, elephants, wild donkeys, hartebeest (an antelope species), hippopotamuses, and auerochs.
UPDATE: NRC 15 May 2008, page 11: Veerle Linseele et al. retract their earlier captive cat statement; they now think these remains were of Felis chaus.
